Sensitivity
The SENSITIVITY register contains the parameter for the multiplier in the DSP. The
Sensitivity is programmable between 4 and 4. For VSUP = 5 V, the register can be
changed in steps of 0.00049.
For all calculations, the digital value from the magnetic field of the D/A converter is
used. This digital information is readable from the D/A-READOUT register.

VOQ
The VOQ register contains the parameter for the adder in the DSP. VOQ is the output
signal without external magnetic field (B = 0 mT) and programmable from VSUP (
100% duty-cycle) up to VSUP (100% duty-cycle). For VSUP = 5 V, the register can be
changed in steps of 4.9 mV (0.05% duty-cycle).
Note: If VOQ is programmed to a negative value, the maximum output signal is limited
to:
VOUTmax = VOQ + VSUP
Clamping Levels
The output signal range can be clamped in order to detect failures like shorts to VSUP
or GND or an open circuit.
The CLAMP-LOW register contains the parameter for the lower limit. The lower clamp-
ing limit is programmable between 0 V (min. duty-cycle) and VSUP/2 (50% duty-cycle).
For VSUP = 5 V, the register can be changed in steps of 9.77 mV (0.195% duty-cycle).
The CLAMP-HIGH register contains the parameter for the upper limit. The upper clamp-
ing voltage is programmable between 0 V (min. duty-cycle) and VSUP (max. duty-cycle).
For VSUP = 5 V, in steps of 9.77 mV (0.195% duty-cycle).
